See my first message for this sentence: "LinuxCNC receives encoder signal and reports the actual position of the motor - it stops the run, when ferror is exceeded." BTW in meantime I started to torture another joint - I am now jogging it back and forth and trying to work out pid parameters and one strange thing is that sometimes in direction to negative end of joint (and I have observed that only in this direction) joint continues to travel at previous speed after the button is released and then in a second or two it would suddenly stop the motion and start to respond to any new jog commands. I do not receive any warning messages about realtime issues. All the time encoder tracks the position correctly - if I bring it back to 0, it is actually in the same spot (plus minus half a milimeter, I cannot measure more precisely) on the machine. -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
